Cerebral Sinovenous Thrombosis due to Hypernatremic Dehydration in a Neonate.

Cerebral sinus venous thrombosis is an uncommon complication of hypernatremic dehydration in neonates. Non-improvement in neurological status even after correction of hypernatremia should lead to suspicion of intracranial complications due to hypernatremia or its overtreatment. Slow correction of hypernatremia, calculated fluid administration, and anticoagulation improve outcome in neonates with CSVT.
